Abstract
Silabicyclo[3.1.0]hexane 2 obtained from silacyclopent-3-ene 1 by dichloroc arbene addition is useful in the synthesis of ring-expanded products, such as silacyclohexa-2,4-diene 3 and 5-alkoxysilacyclohex-3-enes 5. Catalytic h ydrogenation of compound 3 affords silacyclohexane 4. The new heterocycles ave characterized by C-13 and H-1 NMR, as well as mass spectroscopic data. (C) 1999 John Wiley & Sons, Inc.
